Produce Electricity From Wastewater?

“In the latest green energy – or perhaps that should be brown energy – news, a team of engineers from Oregon State University (OSU) has developed new technology they claim significantly improves the performance of microbial fuel cells (MFCs) that can be used to produce electricity directly from wastewater. With the promise of producing 10 to 50 times the electricity, per volume, than comparable approaches, the researchers say the technology could see waste treatment plants not only powering themselves, but also feeding excess electricity back to the grid.”
